Good too, but please also read
help("rcpp.package.skeleton")
and use it to __create a working Rcpp package__ into which you simply copy
your working prototype.
Read the "Writing R Extension" manual for general "how do I package with R"
questions; read the Rcpp docs (and particularly the Rcpp-package vignette
and/or Chapter 5 ("Using Rcpp in your package") of the Rcpp book.
